Firmware package for the MSI U270 netbook, mainboard MS-12451 version 1.0, in a RAR archive of roughly 1.13 MB. The name does not say which images are included, so open the archive and check the file sizes before use. MSI labels its own boards with MS- numbers, which appear on the PCB silkscreen. A dump like this is normally written to the SPI flash chip with a hardware programmer such as a CH341A to recover a corrupted BIOS. Always read and save the original chip contents first, and make sure the image size equals the chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
